Dialogue:
"My husband's going to a casino in central Asia."
"Tibet?"
"Of course, why else would he go!"
By the way I can’t understand the joke…

Perhaps this one will be easier to understand:

A blonde was in Vegas vacationing with friends. She was standing in front of the candy machine and put two coins in, turned the knob and a candy bar fell out.
She picked up the candy bar and put it in her pocket, then she proceeded to put two more coins into the slot and turned the knob, again a candy bar fell out and she put it in her pocket. She put two more coins into the machine and again turned the knob producing yet another candy bar. A man was watching from a short distance away and walked up to her, he said "Excuse me Miss? What are you doing?"
She said, "Duh! I'm winning here!"
